What is a Zone Block?
The block system was developed to make entering the Zone easier. A Zone block is made up of a mini-block from each macronutrient category (protein, carbohydrate and fat). By balancing your mini-blocks in a 1:1:1 ratio, you can easily attain the proper caloric ratio of 40% carbohydrate, 30% protein, and 30% fat without having to measure grams.
